DeSclafani was placed on the 10-day injured list Wednesday with right shoulder fatigue, Andrew Baggarly of The Athletic reports.
The righty labored Monday against an unimposing Arizona lineup in what was one of his worst starts this season. It's possible the division-leading Giants are just giving DeSclafani some extra rest before the last several weeks of the season. More details about his shoulder should become available in the next week or so.
